When the driving road surface condition suddenly changes from dry to wet, the driving wheels will slip due to much lower coefficient of friction, and thus cause the vehicle to skid. Unlike the popular anti-brake system which applies differential braking to wheels, the presented ant-skid Control properly distributes torques to wheels without braking. In comparison with many recently developed an...

This paper approaches the problem of road extraction from three different directions. The first is the use of multiple scales. This combines detailed information of fine scale, like the markings, with abstract information of coarse scale, like the road network. The second direction is the extension of the multi-scale modeling with the context, i.e., the relations to other objects like buildings...

In crash frequency models, frequency by severity level are examined using multivariate count models. In these multivariate approaches the impact of exogenous variables is quantified through the propensity component of count models. The main interaction among variables across different severity levels is sought through unobserved effects i.e. there is no interaction of observed effects across th...

Firms are increasingly interested in transport policies that enable a shift in cargo volumes from road (truck) transport to less expensive, more sustainable, but slower and less flexible transport modes like railway or inland waterway transport. The lack of flexibility in terms of shipment quantity and delivery frequency may cause unnecessary inventories and lost sales, which may outweigh the s...

This paper addresses a bi-modal multi-objective discrete urban road network design problem. The problem includes the simultaneous design of urban road and bus networks in urban areas in which the authorities play a major role in designing bus network topology. The road network design consists of decision making for lane additions to the existing streets, new street constructions, determining th...

The road coloring problem is an interesing problem proposed over 40 years ago by Adler, Goodwyn and Weiss. Hundreds of mathematicians worked on this problem and failed to make the conjecture a theorem. Finally, in 2007, it was proved by a 60-year-old Israeli mathematician, Avraham Trahtman. It turns out the prove was quite simple after Trahtman partitioned the graph into cycles and trees. The d...

Integrated land-use and transport interaction models (LUTI) are praised for their ability to evaluate land-use and transport planning in an integrated and consistent modeling system. However, applications of empirically estimated land use models are rare. This paper will present the application of the Dutch national land-use/transport interaction model TIGRIS XL in a recent land-use and transpo...

This paper focuses on internal quality measures for automatic road extraction from aerial images taken over urban areas. The motivation of this work is twofold: Firstly, any automatic system should provide the user with a small number of values indicating the reliability of the obtained results. This is often referred to as ”self-diagnosis” and is in particular a crucial part of automatic image...
